Thank you Matthew for your response.
The reference material I was reading came from a book titled "Meditations on the Path to Enlightenment" by Geshe Acharya Thubten Loden, the author did not specifically mention, as you will read in the following quote, about other planetary rebirths, yet in my mind this possibility seemed implied in some way, your answer clarified that it is possible if the Karma allows it (also I would like to note that I am remembering the Gnostic Instructor mentioning something about this in an audio lecture albeit very briefly although I cannot recall the exact lecture). The title of passage reads "Continuity of Mind":
"In western countries there is often not a great appreciation of the connection between this life and past and future lives. Reincarnation is not well understood. It is, in fact, very difficult to perceive past and future lives because they represent a very subtle and distant object of knowledge. From life to life there is a complete change of body, country and even realm or universe. As we have difficulty remembering events earlier in this life, it is not surprising that few people are able to remember previous lives, which stretch even further back in time. Further, the transition between lifetimes is difficult, and there are many obscurations which prevent you from directly seeing past and future lives. However even though you are not able to perceive them, you have in fact lived countless past lives and will be reborn again and again in future."
Now for further clarification, so ultimately you are saying that so long as we have the ego present, we will be unable to directly perceive the ultimate reality of what we are and what is outside of us? Although through escaping the Egos temporarily through such experiences as Samadhi we can at least temporarily get a taste of that perception, is this correct? In this case a Samadhi experience in some ways can help us understand some things about the nature of all these things, due to the ego-escape.
